Abstract

The invention discloses electronic equipment and a fan control method. The electronic equipment comprises a baseboard management controller and at least one fan module, wherein the fan module comprises a fan interface, a fan rotor, and a rotating speed monitoring controller which is correspondingly connected with the fan interface and the fan rotor; the fan interface is used for receiving a firstsignal sent by the baseboard management controller through a first interface, and the first signal is used for controlling the current target rotating speed of the fan rotor; and the rotating speed monitoring controller is used for acquiring a second signal of the fan rotor, the current actual rotating speed of the fan rotor is determined based on the second signal, so that the monitoring load ofthe baseboard management controller is reduced.

Description

technical field [0001] The invention relates to the technical field of automatic control, and more specifically relates to an electronic device and a fan control method. Background technique [0002] Electronic equipment generates heat during operation. In order to prevent the temperature inside the electronic equipment from being too high, the baseboard management controller (Baseboard Management Controller, BMC) in the electronic equipment controls the fan in the electronic equipment to run at a certain speed. [0003] In order to ensure the normal operation of the fan, in the prior art, the BMC needs to monitor the running speed of the fan in real time, so as to generate an alarm message in time when there is a problem with the speed of the fan. However, the way that the BMC monitors the fan speed in real time increases the monitoring load of the BMC. Contents of the invention [0004] In view of this, the present invention provides an electronic device and a fan contr...
